Make Bootable DMG or ISO for Mac OSX Lion / Windows EASY!

[Spartacus32145]

I did this w an external hard drive now it says I can only read. Oh and I can't boot from it either.. I hate windows but I figured I'd try it for gaming... Anyways, be careful doing this with an external hd.

[dnlddz1]

How can I make a bootable OSX lion flash from linux? Anyone happen to know?

[p0chilam]

what is the end line when it finishes? coz xp.sp3. is about 713.6 MB...should be faster than 1 or 4 hours..maybe 1 hour but mine is saying "713621504 bytes transferred in 271.347118 secs"

will it continue or finished?

[zhale47]

Yess, thanks!

[Archduk3]

I tried this using both this, and unetboot. Nothing will actually boot with my Samsung notebook, whats the problem?

[pgeske]

I did exactly what you said, but the usb doesn't show up in the boot menu at startup.

[thepopeanator]

if i am making a osx lion USB do i format the drive differently?

[Lviv737]

Made the image,rebooted into rEFIt,tried tostart windows 7u x86 and got "Non-System Disc Press any key to reboot" error.

[RobbieDelacruz]

Okay so it started blinking but after a while maybe 20 mins, it stopped blinking but it not showed in desktop or finder... what do i do now?, is this normal?

[MRLSCPRODUCTIONS]

how do i make a bootable iso/dmg?? basically i have a iso program that is 10gb and i need to put on 2 disks??

[diananavarroo]

does it have to be formatted as MSDOS if you're trying to boot a MAC OSX installation disc?

[JUSTaROKK]

I followed the steps but when the comp boots up this message pops up

This Product is covered by one or more of the following patents: US5,307,459,US5,434,872,US5,73­2,094,US6,570,884,US6,115,776 and US6,327,625

[nilsi1987]

Cant get it to boot. Have installed rEFit and waited until it was finished but it still dont boot. Have anyone got this to work? Give me a tumbs up if YOU got this to work for WINDOWS 7.

[iMeerkatCS]

@nilsi1987 this works for windows 7 i've made a number of bootables. If you need one I can point you in the right direction.

[Archduk3]

@iMeerkatCS I can't make my samsung laptop start from it.

[invaderekim]

@iMeerkatCS im trying that right now can you guide me please.. invaderekim@yahoo.com

[invaderekim]

@iMeerkatCS im trying to make my external HD Windows 7 Bootable... can you please guide me? I'd really appreciate it!! thanks bro

[monikgada11]

how do i know if its working..ok ya ma hard disk is blinking but how do i know when is it done or how much is it done so far..???

Thankss

[iMeerkatCS]

@monikgada11 I wish there was a command which gave you a status but i can't find one. best thing to do is be patient. I'm sure you resolved this but if you didn't let me know.

[iMeerkatCS]

@theSuitMusic I didn't want to get into process pipleline status to not confuse viewers. I tried making this as simple as possible for Lix nubs. ps is a great. I've used it with solaris os. (my favored cloud server :D) Thanks a ton for the input. I might as well toss an annotation in the end of the video. Crediting you of course!

[Augurae]

@iMeerkatCS Man don't fucking listen to @theSuitMusic !!!

Did you at least try the command? It stops the fucking process

[jlkill3r]

@theSuitMusic hey man, great command, just have one question, I know it is working because I canceled it before and seen the content in folder but when I use this command I do not receive the choice for the dd, I do however have a choice between other terminal processes

[pgeske]

@theSuitMusic Doesn't that just end the process? i tried it, and it didn't display the current progress. instead, as i expected, it killed the process, forcing me to erase the usb drive and start over.

[andrefrbk]

@pgeske yeah same here... Make the shit music's comment marked as spam. Its not working.

[bornfordeath55]

@theSuitMusic YOU ARE A CUNT! This stopped the process. should of realised when i was typing fucking SUDO KILL, you're a cunt.

[rhaynesak]

@bornfordeath55 Different version of dd take different sigint signals.  USR1 is a valid sig for some builds. The command for dd to dump info for me is "kill -info process_id"

[foofooface12345]

I do everything and follow the video but a couple minutes after I get the message in a dialogue window: "This disk is not readable by this computer" this is like the 4th time its happened and I always have to erase the drive in disk utility to use it again, anything I can try?

[iMeerkatCS]

@foofooface12345 setup a meeting via my website imeerkat dot com / contact I'll resolve any issues

[ItsGunSon]

This didn't work for me. It wasn't bootable no matter how I messed around with it. I tried changing the partition schemes, and I tried doing it straight to /dev/disk1 and also to /dev/disk1s2.

[jhbeetge]

Hi iMeerkatCS,

Thanks getting back to me.

I did what you said and it went through the whole process, but in the end it said that this USB will not be bootable on a Mac. I tried my luck with rEFIt but it only said Boot error.

What I'm trying to do is install Windows 7 in Bootcamp as a standalone OS, but my superdrive broke again and after weeks of research, I found that Bootcamp won't boot from an external, so now I'm on a mission to have bootcamp boot from a USB. But I'm completely stuck!

[DubstepAndy]

If your harddrive has several partitions on it, note that when you write the dd command you specify it by /dev/diskXsY, where X = disk number and Y = partition number.

[iMeerkatCS]

@DubstepAndy Right on Andy! Thanks for contributing.

[jhbeetge]

dd is /bin/dd

/usr/bin/Type: line 4: type: if=/Users/JHBeetge/Desktop/Win­dows 7 Ultimate/Windows 7 Ultimate.iso: not found

/usr/bin/Type: line 4: type: of=/dev/disk1: not found

/usr/bin/Type: line 4: type: bs=1m: not found

This is what I get time and time again. Any advice? Thanks.

[iMeerkatCS]

@jhbeetge sorry it took me so long to respond i was out of town. from the looks of it your running a linux distro. check out unetbootin. great frugal drive solution thats cross platform. if you need help installing the deb let me know. :)

[BoszLightyear]

@jhbeetge Try using a capital M (bs=1M instead of bs=1m). That's what the ubuntu website recommends to fix that problem. Some computers work a bit differently.

[DarkIighter956]

Just curious, how do I know when it's done burning? I'm currently using a PNY 16gb flash drive but I don't see any blinking lights.

[leith941]

@DarkIighter956 Hey man you stole my question! :P

same problem here, I'm currently using macbook pro & 4 Gig flash Ram (USB) and i don't see any blinking light! how am i supposed to know if the operation is processing or not? :P

[ItsGunSon]

@leith941 the terminal window will show you it's done. It will spit out some info like how long it too, and it iwll give you a new command prompt.

[iMeerkatCS]

@ItsGunSon My only guess is the iso is missing

[jlkill3r]

Can someone tell me what the bs=1m means?

[iMeerkatCS]

@jlkill3r If the block size (BS) ends with a ``b, ``k, ``m, or ``g, the number is multiplied by 512, 1024 (1K), 1048576 (1M), or 1073741824 (1G) respectively.

[iMeerkatCS]

@jlkill3r Very glad someone asked about the DD command! In broad terms dd if=(source) of=(target disk) bs=(byte size) ("USUALLY" some power of 2, and usually not less than 512 bytes (ie, 512, 1024, 2048, 4096, 8192, 16384) but can be any reasonable whole integer value. The default block size for dd is 512 bytes, the operand bs= is used to increase the block size. Bigger block sizes will greatly increase the speed of the copy to a point.

[jlkill3r]

wow, this was indeed a great help, thank you

[filmmakerdude]

thanks man, your awesome. my 2006 imac didnt want to boot from usb so Im currently using the same instructions to make a bootable partition on an external HDD - thanks again dude

[iMeerkatCS]

@filmmakerdude No problem filmmakerdude glad I could help!

[tamer27antepli]

i dont understamd the point of hackintosh on a netbook

becouse you need a mac

[xbsl123x]

change title - remove windows, you didnt say how to do it on windows. good video nonetheless.

[basharalkurdi]

I have macbook pro with LionOS and want to install W7 on it. I followed your steps and still the rEFIt didn't recognize the flash drive as a bootable drive for W7!

What should I do?

[NinjaNZL]

@basharalkurdi i also have a macbook pro with lion. i am having the same problem with refit. have you had any luck yet?

[MsPoiu89]

@basharalkurdi same problem! bump.

[basharalkurdi]

@MsPoiu89 so any solution?

[abelchavez]

i was doing this to install win 8 preview but the device isn't bootable when i reboot with option key.. any solution? thanks for the terminal codes btw :)

[jakedaviesamsterdam]

Thank you, it was very useful for me

[TheDeanoWeKnow0]

Followed guides exactly as shown here however after the job was finished the USB drive had been reformatted to UDF from fat 32, now I try to erase the usb again and the UDF portion will not go away, any ideas? BTW runnning Snow Leopard with an iso of 64bit Win 7

[exklimexklim]

man i have a cuestion . can i do the same thing for boot a new version of mac os? or i have to change the format?

let me know thanks

[Ksiemons]

Hey Meerkat (is that Dutch btw) I followed your instructions and typed in the commands in the Terminal. It might take a while because I want to boot Windows 7. I checked in again and Terminal shows the following:

3568+1 records in

3568+1 records out

3741720567 bytes transferred in 466.446861 secs (8021751 bytes/sec)

This left me with 2 questions: 1). Does this mean that it's done or do I see the USB HDD pop up on the desktop? 2). To install Windows, do I use Boot Camp?

Anyways, thanks!

[dalynthesk8r]

scince i don't have a windows 7 dvd to use with biitcamp will my macbook pro boot from a flash drive?

[datafreak667]

@dalynthesk8r macbook pros coom with an sd card slot so download windows 7 homepremium iso and do this onto an sd card use bootcamp assistant to partition your drive then MAUNULY restart your laptop and hold down the alt/option key after you hear the mac startup sound then find you sd card and click enter

[bigtownbucks]

thanks for majing this it helped me out a lot!

[22cxiong]

@iMeerkatCS On Mac

[gtrophy1]

What a yinzer... "What time yinz wanna goo dahn err to format dem iso's"

[iMeerkatCS]

@gtrophy1 Trolling is cool... right?

[avensons007]

question is if it is in UDF is it fine or not?

[arkeidian1]

Thumps up if he looks like shia labeouf (at least from far away)

[iMeerkatCS]

@arkeidian1 hahaa i've heard that before..

[mexicanassassin1000]

@arkeidian1 damn, i was gonna put a comment like that, then i saw urs :P

[BreadForButter]

how do i know when its done????/?

[saudestyle]

So, if I just finished putting my XP .ISO onto my flash following your steps, and my computer didn't recognize it when I rebooted, what do you suppose is the problem?

[TheZwergkralle]

@MeerkatCD thanks for your answer.

I did it the same way like your video shows. I erased the stick with the Diskutility. In "Format" i choosed MS-Dos-Dateisystem FAT and the stick was erased. I checked it again an it was the right Format FAT/32. Then I do all the other steps and everything is ok... but when the USB Stick is ready (7 hours later) the format is again UDF. So I have no idea why the format of the Stick changes from FAT32 to UDF during the Process. Have you got an idea what i can do?

@thezwergkralle ALL windows bootable partitions need to be formatted as FAT/32

To edit that cfg file you need to change the file permissions here's how: (apologize about the text formatting I'm doing this from my phone)

Click Start, click My Computer, and then locate the file or folder where you want to set special permissions.

Right-click the file or folder, click Properties, and then click the Security tab.

Click Advanced, and then use one of the following steps:

3.) Then I want to Install win7 with Bootcamp on the iMac (Lion OS X).

Is that possible with the USB Stick with the UDF Format or only with a Stick with Fat format?

[TheZwergkralle]

2.) First I want to use the stick for install win7 on a PC. Before I want to boot the PC I want to check if the PC (with XP) is able to read the USB Stick. But it is not possible. Is the Problem the UDF Format? Have I to make a fat Partition by disk utility before I write dd... in the terminal?

[TheZwergkralle]

I did it and have now an USB Stick with Win7. The format is UDF.

Now I have three questions:

1.) I want to edit the ei.cfg in the "sources" folder by using the Prog Textedit.

But it is not possible because there`s a message. the file "ei.cfg" is Protected.

What can I do for edit it on the usb Stick?

[djcrawleravp]

Yo save my day man!! thanks a lot!!

[seannux]

i already created a win7 USB disk. but my macbook pro cannot identify it as bootable disk. and i cannot set my start up boot order to USB. need help.. thanks

[br0ad456]

anyone booted a pc with this? does it work???

[iMeerkatCS]

@kuyajhet I definitely can. It'll be up by tomorrow at the latest.

[kuyajhet]

can you make a tutorial for windows?



[sardo97]

Thank you so much this helped a lot.

[iMeerkatCS]

@designproject22 depending on how old the system is and the bios there might not be an option for USB booting. Lemme know the model number and try updating your bios.

[iMeerkatCS]

What kind of computer?

[designproject22]

I cannot find USB in my BIOS boot order. There is a removable, that is already number one and it still does not start up. I think the removable is only for a floppy. How can I find the USB drive?

[eloscurosecreto]

use the same commands for dcfldd instead of dd, you'll be able to see the progress. Install homebrew and pull down dcfldd, as it is not installed on OS X by default.

[iMeerkatCS]

hold f8 and select your flash drive

[ChrisAdSim]

Nothing happens when i hit f2 during startup..?

[femozaky2000]

I need an OS man, Lion on Windows can you help please?

thanks

[wheredmyusernamego]

@femozaky2000 do a google search on 'hackintosh'

[iMeerkatCS]

Access your bios. Usually pressing f2 at start up. Scroll through using the keyboard and find the boot settings. Then change the boot order so USB is first.

[iMeerkatCS]

You have to access your BIOS and change your boot order. Usually holding f2 at a reboot startup will do the trick.

[Marci0306]

How do you boot on usb?

[iMeerkatCS]

Try this in terminal:

diskutil eraseDisk HFS+ newdisk disk1 (may be disk2 or maybe 3 depending on the mount point. Type: diskutil list and find your flash drives mount point.

[swclikewhut]

how do you remove the file when you're done with it so I can use the USB drive for storage again? Stuck in read only mode and 'erase/restore' options in disk utility is grayed out

[tobay17]

any chance you could tell me how i could use this to install windows via bootcamp? I have the .iso and i am following as your instructions to put it on the USB. Now I'm just wondering once that is done, do i just run bootcamp and it will recognise it as a the bootable software?

[master1335]

Thank you for the simplest easiest way guide on web.. I'm not wondered I'm doing something wrong...

[iMeerkatCS]

Format the disk to fat32

[Taocu]

Hey, thanks for a great tutorial.

If I do this for Win7, do I format the disk as NTFS-3g or do I stick with MS-DOS FAT as you did here?

Cheers

[iMeerkatCS]

Since the Windows 7 iso is so large it could take up to 2 hours to partition

[SHUR1312]

Dude, I did everything on my mac (I have lion) and i'm trying to get windows 7 so i can use the boot camp thing. How am I supposed to know when it's done? Please respond asap! Thanks!

[iMeerkatCS]

Axel sorry it took me a while to get back to you. If your partitioning windows 7 it's gonna take an hour+

[axel72893]

bro, after i did what u said at the video, how long do i need to wait and how do i knw whether the process is done or not

[Kikirini]

This did solve my problem of not being able to burn the iso to the flash drive... unfortunately it's still not bootable. Any advice? Thanks <3

[sejlatrebo]

I have the same problem here... trying to burn DOS to the usb since my cd-rom doesn't work... and I really need DOS for not-working PC

[mrti3]

Amazing. Thanks dude !

[iMeerkatCS]

How big is the xp iso? If you need an xp iso that worked for me lemme know

[dartheniak]

@iMeerkatCS 617.8MB ... so maybe it's the iso? if u can pm me a link I'd really appreciate it :)

[dartheniak]

argh... for some reason it's not working here. it copied everything and I can see the volume mounted... but it seems it doesn't see it as bootable. maybe cuz I didn't mod the winxp iso? or should it work with an untouched iso?

[iMeerkatCS]

@dartheniak you can definitely use disk utility to unmount. However, like you said I like to use terminal cuz cmd line Unix is more fun. Haha. I'm working on making this into a shell script GUI. Have yet to find anyone who has made this a program on Mac. I know slysoft has made great clonedrive software for pc. If anyone would like to apply input or help on my endeavor send me an email.

[iMeerkatCS]

@iMeerkatCS hey i tried sending a message and your on friend lock. email me contact@imeerkat.com

[dartheniak]

great video! thanks for the up. just a couple ov doubts:

1. do u really need to use terminal to unmount the disk, or doing it through the diskutil GUI is also fine enough? (using terminal is always cooler but I just want 2 have this clear.)

2. the iso u used is untouched or did u have to mod it?

[iMeerkatCS]

Awesome. For some reason disk utility doesn't do the job making bootables. I haven't found a free source program either. I might have to make one.

[wharrgalable]

To get a usb stick working as a Win 7 installer (for a Boot Camp partition) this trick is the missing link - thanks !

[joboskop]

thanks dude..

[myasshole404]

This guy knows what he's doing. He deserves a notice for it.

[SpartanGroupAlpha]

Great stuff! The forum idiots need to learn how to search YouTube every once in a while :D

I ran through at least 50 forum suggestions that didn't work, yet this solution worked on the first try! Thanks!

[iMeerkatCS]

@GenuineSwaggerr Awesome. I'm glad I could help! Love you too hahaa (no homo). If you need any computer help message me. Thanks for the support and feedback!!

[GenuineSwaggerr]

THANK YOU SOOO MUCH! nothing else was working! i was getting errors and everything, i will be favoriting and repping this video everywhere possible dude. I love you, i accidently wiped my old OS for backtrack and had to return it to windows 7 but NOTHING was working, you saved my ass BIG TIME. i love you man

no homo

[iMeerkatCS]

@jonCR00K no problem jon glad I could help

[DJImpuls3]

Hey bro..I made my usb flashdrive bootable through windows and it's already mounted with the iso. I used the USB DVD tool from microsoft to make the usb mountable. Do I do the same as you did by erasing the usb on windows, copy the iso onto it, copy it to my macbook's desktop and then do what you did??

[iMeerkatCS]

@DJImpuls3 Exactly. Just make sure you Erase and format the USB to FAT32.
